i used to get this white rectangle strip covered a movie picture when trying to capture a protected DVD movie through my stand alone DVD player using graphic card. After installed a few programs: they are Tweak WinDVD, TVtool and some other stuff. My graphic card is Leadtek Geforce4 MX myvivo (nVidia chipset) edition. Now i can capture any movie perfectly. I don't know what turned off the Macrovision on my graphic card.

If anyone has the same problem try install Tweak Windvd. i think that does the trick ....... well maybe anyway....
